Muncies are easy to find. Just look at the input shaft, you want a 10 spline and the output shaft will use the same yoke as Turbo 350. A T10 will also work. Depending on what year your 350 is, there is a lite weight flywheel that works on the one piece seal engines. It weighs half of what a normal flywheel weighs. You can shave some weight off with the right combination of parts.
